blender cycles render bake doesn't uses world emitted light
Second edit, I finally found the cause of the problem, I have in blender 2 objects, one is engulfing the other this engulfer is a tube with a weird shape, the thing was that I had this tube as "restrict from viewport visivility", in the "preview" the tube was not affecting the rendered image but in the "bake" it was, can this be considered a bug?
